1 Claim.

This invention relates to new and useful improvements in closure controlled lights, involving a closure operated switch,especially adapted for automatically lighting the interior of coal bins, closets and other enclosures, when a closure thereto is opened.

The principal object of the present invention is to provide a closure operated switch structure for controlling a light automatically upon operation of the complementary door or other closure.

Other objects and advantages of the invention will become apparent to the reader of the fcllowing description.

In the drawings- Figure l represents a fragmentary outside elevational view showing a closure and the approximate location of the switch means.

Figure 2 is a fragmentary vertical sectional view taken substantially on the line 2-2 of Figure 1.

Figure 3 is a Vertical sectional View through the switch structure.

Figure 4 is a horizontal sectional View taken substantially on the line 4-4 of Figure 3.

Figure 5 is a transverse vertical sectional view taken substantially on the line 5-5 of Figure 3.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 1 that numeral 5 denotes a door frame which includes Vertical side members 6 and a horizontal top member l.

Numeral 8 generally refers to the switch which makes up the present invention. This switch structure 8 includes a plate 9 which goes against lthe underside of the top member I of the door frame 5. 'Ihe switch further includes a box IIJ open at its top and provided with a side flange II. The side flange II and the plate 9 have registering openings I2 through which screws or other securing elements I3 can be disposed for securing the switch in place as shown in Figure 2. It is preferable that the Ibox I0 have open sides so that the parts can be readily reached for repairs and replacement.

The bottom of the box I0 has a guide rib I4 extending longitudinally thereof which is straddled by the lower bifurcated end of a slide plate I 5, the upper end of which has a plunger I5 projecting therefrom and through a bushing of insulation in a plate I'I and also through an opening in one edge of the box I0.

As can be seen in Figure 3, this plunger I6 actually projects from a plate I 8 of insulation carried by the plate I5.

The plates I'I and I 3 of insulation have contacts I9, 2D thereon to which connect conductor wires 2 I, 22, respectively.

The plate I5 with its contact 20 is urged into position With the contact 20 engaging the contact I9 by a compression spring 23 interposed between the plate I5 and the back wall of the box I0.

It can now be seen, that the plunger I5 will normally bear against a complementary door 25, with the contacts I9, 20 in spaced relation, and the spring 23 under compression.

When the door 25 is open, the plunger I6 is released and the eifect of the sprmg 23 will force the plate I5 to the left in Figure 3 until the contact 20 engages the contact I9, closing a circuit including the conductors 2l. 22 and a light and source of current (not shown), thus energizing the light and illuminating the enclosure.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the claimed as new is:

In combination with a closure, a switch, said switch including a box, a plate of insulation in the box, a contact on the plate of insulation, a slide structure having one end bifurcated, a guide rib in the box and which the bifurcated end of the slide structure straddles, a plunger projecting` from the slide structure to the exterior of the box, and a compression spring in the box for normally urging the slide structure and plunger toward the closure, said structure including a plate of insulation and a Contact thereon in the path of the first-mentioned contact.
